Story highlights

The Fab Four refused to play before a segregated audience in a 1965, according to a Beatles contract that was auctioned off for $23,000 on Tuesday.

The contract -- signed by Beatles manager Brian Epstein -- was for an August 31, 1965, show at the Cow Palace in Daly City, California. The concert was part of a Beatles' third major tour of the United States, following the release of "Help!"

In the document, it specified that the band "would not perform in front of a segregated audience" and came the year after the Beatles initially refused to play a segregated show at the Gator Bowl in Jacksonville, Florida. The band performed after city officials allowed the crowd to be integrated.

It also called for at least 150 uniformed police officers for protection and for "$40,000 guaranteed against 65% of the gross box office receipts over $77,000."

The contract was auctioned by Nate D. Sanders Auctions in Los Angeles. The document went for well-above the pre-auction estimate of $3,000-$5,000.
